Jubjub Curve
This crate provides jubjub curve arithmetic and also supports fully no_std and parity-scale-codec.
Specification
The Jubjub curve is one of twisted edwards curve.
- Twisted Edwards Curve
$$ ax^2 + y^2 = 1 + dx^2y^2 $$
- Addition Law
$$ (x_3 = \frac{x_1y_1 + y_1x_1}{1 + dx_1x_1y_1y_1}, y_3 = \frac{y_1y_1 + ax_1x_1}{1 - dx_1x_1y_1y_1}) $$
Test
$ cargo test
